UNIT STEAM OR HOT-WATER RADIATOR.

Application filed March 4, 1926; Serial No. 92,810;

This invention relates to unit steam or hot water radiators and more particularly to a stez'im or hot water radiator which embodies its own heating plant.

An important object of the inventionis the construction of the combustion chamber so that a maximum heating surface is afforded.

A further object of the invention is to pro vide a construction whereby the combustion chamber. may be conveniently vented without mar-ring the appearance of the finished radiator. a i

A still further object of the invention is to provide an outlet vent for the radiator of such character-that back draft, such as often occurs in a faulty chimney, is prevented from reaching the combustion chamber.

A turth'er'objectlof the invention is to provide a construction; whereby theseobjects may be attained with but a slight modification of certain of the sections of the radiator.

These and other objects I. attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is" shown a preferred embodiment of my invention and wherein Figure 1 is a rear elevation of a radiator constructed in accordance with my invention;

Figure 2' is a side elevation of an ordinary unit;

Figure 3 is a vertical sectional View through a vented unit;

Figure 4 is a section on the line H of Figure 3 I a Figure 5 is a transverse sectional view through the lower end of one section of the radiator on the line 5-5 of Figure 4;

Figure 6 is a rear elevation of the vent header; a t

Figure 7 is an end elevation thereof;

Figure 8 is a view of a modified header;

Figure 9 is a topi plan of the header cap,

the pipe connectionbeing indicated in dotted 1 lines.

Referring now more particularly to the drawings, the radiator consists of a plurality of units including intermediate units subdivided intovent units 10 and ordinary units 11. and a pair 0t end units 12'. Each ordinary unit 11 has at its upper and lower ends cored chambers 13 and 14, the chamber 14 at the lower end of the unit being subdivided by atransverse partition wall 15 to produce i a third or combustion-section chamber 16.

The chambers 13 and 14 are connected by aligned vertical tubes 17. The chambers 13 and 14 each have in their side walls openings 18 surrounded by thimble seats 19, for the reception of the ends of thimbles 20 forming the connections between adjacent units. The chamber 16 has in its opposite side walls openings 21 to permit the insertion of a burner 22 and to provide exit openings for the products of combustion. The bottom wall of the chamber 16 is. provided with an openin 23 for the entrance of air and. of which t e openings 21. are extensions. Each section has on opposite side faces thereof an inverted U-shaped rib- 24, comprising an intermediate portion 25-WhlCl1i is arranged at a point intermediate the ends of the tubes or columns 17 and spaced downwardly ex tending side portions or legs 25' which extend approximately tothe bottom of the section at opposite sides of the opening 21. The ribs at opposite sides of the section merge with each other through the interstices 26 between. adjacent columns; 17.

In the assembled radiator, adjacent edges of the ribs 24 come into contact with one: another and since the space between the sections below these ribs is. in communication with the combustion chamber 16 through the openings 21, it follows that the products of combustion from the burner 22 will. pass upwardly between; adjacent faces of the radi ator sections and are permitted to pass about the lower ends of the columns 17;

Each vented section 10 is identical with the section hereinbefore described with the exception of the fact that, one of the tubes, connected with 17, has each end closed by partitions walls 27 and 28. Adjacentits lower end, this tube is cut away at its inner side, as at opening 29,

so that the interior of the chamber .30 formed by the tube is in com munication with the up er end ofthe combustion chamber, as defined by the ribs 24. The outer face of the tubes 17- is provided with outlets 31 and 32 at-the upper and lower ends of the chamber 30. The end sections 12' are identical. with the sections 11 with the exception of the fact that the outer faces thereof are made plain. and free from. the ribs 24 and. the openings below the intermediate portion of the ribs 24 at the inner faces are filled by a web cast. integral with. the tubes 17 Thus, these sections serve to seal the ends of the combustion chamber; The sections 19, 11 and 12 are held in assembled re iation by" the usual bolts 33;

in small radiators, where only a few sections are employed, but two of the vented sections 10 are used and these are generally placed at the center of the completed radiator. ihe upper openings 31 are connected by a vent cap 34, the cover of which, indicated at 35, is adapted for engagement with a flue pipe 36. In longer radiators, such as are at present illustrated, two of the vented sections are employed at the center of the radiator and a single vented section adjacent each end of the radiator. A. vent cap 3? is employed which is similar to the vent cap 8%: with the exception of the fact that. it has openings 38 in its end walls. 'llhese openings are connected with the vent openings of the sections 10 adjacent the ends of the radiators by suitable manifolds til It is pointed out that with the construction hereinbefore set forth, not only is an efiicient heating of the fluid contents of the radiator obtained, but back draft to the combustion chamber is also efiectually prevented. Any down draft which may enter through the openings 31, in passing through the elongated chamber 30 will, in preference to changing its direction and buckin the heated gases rising through the opening 29, pass out through the opening 32 to the room. It is also pointed out that those tubes-i user as stacks in the sections 10 act with the remaining tubes to supply heat to the room due to the fact that the t are heated from the ases arising from the combustion chamberw It will be obvious that the construction hereinbefore set forth is capable of certain range of change and modification without materially departing from the spirit of the invention and I accordingly do not limit myself to such specificstructure except as hereinafter claimed.

l.
